Resilience in Radiotherapy Services During the COVID-19 Emergency: Collaboration Between the Regional Radiation Oncology Departments of Lazio, Abruzzo and Molise.

AIM: Radiation therapy is a cornerstone of oncological treatment and oncological patients show greater risk of developing complications related to COVID-19 infection. Stringent social restrictions have ensured a significant reduction in the spread of the virus, but also gave rise to a number of critical issues for radiation oncology wards. For this reason, the Directors of the Radiation Oncology Departments (RODs) of Lazio, Abruzzo and Molise regions shared their experience and ideas in order to create a common document that may assist in facing the negative impacts of the pandemic on radiation oncology wards and patients. PATIENTS AND METHODS: The study was conducted according to the Estimate-Talk-Estimate method. Five issues were proposed and rated. Among approved issues, statements were proposed anonymously, then harmonized and finally voted on according to a Likert scale from 1 to 9. Those for which an agreement of 7-9 was observed were finally approved. RESULTS: The document was developed with 42 statements dealing about safety measures for patients and staff, organization of clinical and work activities, usage of Information Technology systems for meetings/smart working. An agreement was recorded for 34 statements. CONCLUSION: This document sets out some recommendations for RODs and can provide valuable management information for Oncological Radiotherapy wards.

Policies for reirradiation of recurrent high-grade gliomas: a survey among Italian radiation oncologists.

PURPOSE: To assess the contribution of Italian radiation oncologists in the current management of recurrent high-grade gliomas (HGG), focusing on a reirradiation (reRT) approach. METHODS: In 2015, the Reirradiation and the Central Nervous System Study Groups on behalf of the Italian Association of Radiation Oncology (AIRO) proposed a survey. All Italian radiation oncologists were individually invited to complete an online questionnaire regarding their clinical management of recurrent HGG, focusing on a reRT approach. RESULTS: A total of 37 of 210 questionnaires were returned (18% of all centers): 16 (43%) from nonacademic hospitals, 14 (38%) from academic hospitals, 5 (13%) from private institutions, and 2 (6%) from hadron therapy centers. The majority of responding centers (59%) treated ≤5 cases per year. Performance status at the time of recurrence, along with a target diameter <5 cm and an interval from primary radiation ≥6 months, were the prevalent predictive factors considered for reRT. Sixty percent of reirradiated patients had already received a salvage therapy, either chemotherapy (40%) or reoperation (20%). The most common approach for reRT was fractionated stereotactic radiotherapy to a mean (photon) dose of 41.6 Gy. CONCLUSIONS: Although there were wide variations in the clinical practice of reRT across the 37 centers, the core activities were reasonably consistent. These findings provide a basis for encouraging a national collaborative study to develop, implement, and monitor the use of reRT in this challenging clinical setting.

Low dose rate brachytherapy (LDR-BT) as monotherapy for early stage prostate cancer in Italy: practice and outcome analysis in a series of 2237 patients from 11 institutions.

OBJECTIVE: Low-dose-rate brachytherapy (LDR-BT) in localized prostate cancer is available since 15 years in Italy. We realized the first national multicentre and multidisciplinary data collection to evaluate LDR-BT practice, given as monotherapy, and outcome in terms of biochemical failure. METHODS: Between May 1998 and December 2011, 2237 patients with early-stage prostate cancer from 11 Italian community and academic hospitals were treated with iodine-125 ((125)I) or palladium-103 LDR-BT as monotherapy and followed up for at least 2 years. (125)I seeds were implanted in 97.7% of the patients: the mean dose received by 90% of target volume was 145 Gy; the mean target volume receiving 100% of prescribed dose (V100) was 91.1%. Biochemical failure-free survival (BFFS), disease-specific survival (DSS) and overall survival (OS) were estimated using Kaplan-Meier method. Log-rank test and multivariable Cox regression were used to evaluate the relationship of covariates with outcomes. RESULTS: Median follow-up time was 65 months. 5- and 7-year DSS, OS and BFFS were 99 and 98%, 94 and 89%, and 92 and 88%, respectively. At multivariate analysis, the National Comprehensive Cancer Network score (p < 0.0001) and V100 (p = 0.09) were correlated with BFFS, with V100 effect significantly different between patients at low risk and those at intermediate/high risk (p = 0.04). Short follow-up and lack of toxicity data represent the main limitations for a global evaluation of LDR-BT. CONCLUSION: This first multicentre Italian report confirms LDR-BT as an excellent curative modality for low-/intermediate-risk prostate cancer. ADVANCES IN KNOWLEDGE: Multidisciplinary teams may help to select adequately patients to be treated with brachytherapy, with a direct impact on the implant quality and, possibly, on outcome.

Radiotherapy following surgery in keloid treatment: our protocol.

BACKGROUND: Despite the wide availability of literature on keloids, their onset is not completely understood. Several protocols have been described to treat keloids, but none are considered to be a gold standard. In this paper, we will report our experience treating recurrent keloids with surgical excision, followed by immediate postoperative radiotherapy, focusing on the irradiation protocol, to better define the treatment schedule, dose, and results. METHODS: From September 2009 to July 2012, 10 patients were referred to our department because of unresponsive keloids. All patients underwent 6-MeV electron beam radiotherapy, up to a total dose of 20 Gy, 24-48 hours after radical surgical keloid excision. RESULTS: Three patients had excellent results, while 5 patients had good results and 2 had moderate results; none of the cases had poor results. No major adverse events were observed. Small keloids can be treated with non-surgical therapy or radical excision, although followed by an adjuvant therapy. Radiotherapy seems to be a better adjuvant approach. The mechanism for the radiotherapeutic prevention of keloids is still poorly understood. It may act by controlling collagen synthesis through the elimination of abnormally-activated fibroblasts. CONCLUSIONS: From our results, postoperative electron radiotherapy is an effective and well-tolerated treatment to prevent keloid recurrence, especially in patients with bulky keloids or recurrent disease.

Phase II study of fixed dose rate gemcitabine as radiosensitizer for newly diagnosed glioblastoma multiforme.

PURPOSE: In order to evaluate the activity of gemcitabine as radiosensitizer for newly diagnosed glioblastoma multiforme (GBM), a prospective single-center phase II study was conducted. METHODS: Eligible patients were required to have histologically proven GBM with evaluable and/or measurable disease after surgery. They were treated by standard cranial irradiation plus concomitant fixed dose rate gemcitabine given intravenously at 175 mg/m(2) weekly for 6 weeks. After chemo-radiotherapy, irrespective of tumor response, patients went on to receive oral temozolomide at 150-200 mg/m(2) for 5 days every 28 days. RESULTS: Twenty-three patients were enrolled. Median age was 57 years (range 43-72) and median Karnofsky performance status was 90 (range 70-100). Seventeen patients had received subtotal resection of the tumor, while six patients had biopsied-only tumors. Four patients responded to treatment (17.5%) with additional 14 (61%) experiencing stable disease for an overall disease control rate of 78.5%. Median progression-free and overall survival were 6.8 and 10.1 months, respectively. The concomitant radiotherapy-gemcitabine combination was well tolerated and severe adverse events were rare, consisting of grade 3 neutropenia and hypertransaminasemia in two cases each. Twenty patients were assessable for methylguanine methyltransferase (MGMT) promoter methylation, 11 of which were found methylated. In the methylated and unmethylated cohorts, disease control was obtained in 10/11 patients (91%) and 7/9 patients (77.5%), respectively. CONCLUSIONS: Concomitant radiotherapy-gemcitabine is active and well tolerated in newly diagnosed glioblastoma multiforme. Activity is observed both in tumors with methylated and unmethylated MGMT promoter.
